Cartridge module of hollow fiber membranes
Disclosed is a cartridge module of hollow fiber membranes, which can be easily mounted on and dismounted from a module mounting frame, and allow a process for removal of the inter-membrane clogging to be performed in an effective and simple manner. The cartridge module is mainly characterized in that a water collecting header has an opened first collected water outlet, which is located at the upper portion of the front surface of the water collecting header and can be opened and closed; and a closed second collected water outlet, which is located at the lower portion of the front surface of the water collecting header and can be opened and closed. The inter-membrane clogging can be very simply removed by dismounting, turning upside down, and remounting the cartridge module.
1. A cartridge module of hollow fiber membranes comprising a hollow fiber membrane member and a cartridge frame, wherein:
the hollow fiber membrane member has first and second tubular manifolds which are vertically spaced apart from each other in parallel relation; and a plurality of hollow fiber membranes which make fluid connection between the first and second tubular manifolds,
the cartridge frame has a water collecting header; a supporting plate that is spaced apart from and parallel to the water collecting header; and fixing bars that combine the water collecting header and the supporting plate,
the water collecting header has a plurality of water collecting inlets which are located side by side in a horizontal direction at the upper and lower portions of the rear surface of the water collecting header; an opened first collected water outlet which is located at the upper portion of the front surface of the water collecting header, and can be opened and closed; and a closed second collected water outlet which is located at the lower portion of the front surface of the water collecting header, and can be opened and closed,
a flow channel for collected water, which vertically extends in the interior of the water collecting header, is formed to be in fluid-communication with the water collecting inlets, the first collected water outlet, and the second collected water outlet,
the supporting plate has a plurality of fixing recesses which are arranged side by side in a horizontal direction at the upper and lower portions of the front surface of the supporting plate,
the opposing ends of each of the fixing bars are attached to sides of the water collecting header and the supporting plate, respectively, and
the hollow fiber membrane member is vertically mounted in the interior space of the cartridge module which is defined by the cartridge frame, and the opposing ends of each of the tubular manifolds of the hollow fiber membrane member are coupled to the water collecting inlets of the water collecting header and the fixing recesses of the supporting plate, respectively.
